To this end, a ratchet wheel 33 may be keyed on the shaft 30 and have a ratchet pawl 34 coact therewith to slip past the same during its proper Vmovement Vand to arrest the improper movement thereof.' AA brake band 33a surrounds wheels 3.3 and is under appropriate control of lever 33t andvis of the usual `automobile type. Said lever 33b comesV directly under the frame' of the machine adjacent sprocket wheel 29 with asharp L-bend and then direct to the front of the machine at the operators command.

The drum for the drilling cable isi'shown at 35 and is keyed on a shaft 36 journaled'in bearings 37 on the-beams 11. This drum has i va gear wheel 38V rigid therewith or keyed on ,i shaft'36with whicha gear wheel'39isv adapted to mesh. Said gear wheel 39 is slidable on ,andl rotatable with the shaft` 30 in order to mesh and demesh with the said gear wheel '38, being adapted toy be shifted by any suitf thereto as by hinges 43s'o that said frame may be moved into parallelism with the base 10 while the partskare being transported or Vmoved from place to place and as suggested in Figure 4.` Y Said derrick comprises beams 45 and 46, bolted together at 47 in -partly l. foverlappingvand offset relation. The parts of thederrick and the posts 41l are prefer vably y outwardly inclined/*and 4upwardly di- 0j vergedf TheV bars 46 engage'the outer surfaces of the posts 41 to generally reenforce l 'the derrick when in drilling or operative position'.`

` At vthe, other end of the base 10, post/S48 are providedfand when thederrick is erected, brace rods 49 are'detachably fastened to the yposts 48 andthe bars45, in any suitable Inanner, as by means of bolts 50.V In addition,

brace rods 51 may be detachably bolted at'52 vtothe base lOvand the bar 46. i j yAstationary shaft 53 spans the posts 41 at p ltheir top and anjidler lpulley 54is journaled thereon. l. Angle` irons 56 are pivotally or looselyjinountedat one end on the shaft 53 and'at the. other end have a shaft 56 rigidly connected thereto and yon which 'a pulley 57 vis journaled. YPivotally connected to 'the shaft 56 isa spudding or drilling pit-man 58 4 by rods or. shafts 61 and 62 on which pulleys 63V and 64 are journaled, respectively.

which-by means of a wristpin 59 may be adjustably connected to anyoneof a series of openings() inthe crank 26.

'At the'topy of beams 45, they are spanned the drum 35 over pulley 54, pulley 57 and pulley 63 to the well hole.

The sand line is shown at 66 and passes from the sand reel druml 30 over the'pulley 63 to the well hole.

When the device is being transported from place to place, it may be carried in a wagon, on a truck or tract-or or otherwise since it occupies minimum space. rl`he derrick may be swung toy horizontal position as suggested in Figure 3, with the beam 45 engaging the posts or krests 48 in order to support them. It is to be understood that as the various parts are detachably connectedthose interfering with .the said operation may be removed prior to the collapsing or folding of the derrick.

The derrick from the position of Figure 4 is adapted to be elevated by power from the machine and to this end, a cable 67 is adapted to be connected to the drum 32 on the calf reel shaft 30, which cable passes ,through and over pulley 68 and 69, respectively'carried by the frame 10 and the derrick adjacent the lower end of the latter. As

result Aof this construction, tensioning vof the cable 67 will elevate the derrick.

If desired, braces 70 may be detachably bolted as at 71 to the base 10 and the posts or rests 48.

In cases where drilling is to be effected at maximum depth, that is between 200 ft. and 800 ft., usually, the attachment Villustrated in Figures 5 and 6 is used. This attachment consists of a beam 80 which is detachably connected at 81 to the shaft 53 and Yjournaled on the latter, such beam 80 supplanting the beam or rod 55. @ne end of the beam 8O in this instance is pivotally connected to the' shaft 56 and from the other end of the beam, a temperr screw device used in deep drilling, as suggested at 82, is used. This device constitutes no part of the present vinvention and accordingly is not specifically shown. A trussrod or brace 83 is provided for beamk 80, extending yfrom adjacent one end thereof to adjacent the other end thereof.

Changes may be resorted to provided they fall within the spirit and scope of the invention.
